Description

Technical Field

[0001] The present invention relates to the technical field of wall-mounted air conditioners, and specifically provides a wall-mounted air conditioner and a control method thereof. Background Art

[0002] A wind deflector is provided at the air outlet of the indoor unit of a wall-mounted air conditioner. The wind deflector can rotate up and down to adjust the air outlet direction. Since the wind deflector is arranged inside the air outlet, this structure limits the adjustment range of the air outlet direction. For example, in Figure 1 , the wind deflector can only tilt the air outlet direction upward by a certain angle and cannot continue to adjust the wind direction upward; in Figure 2 , the wind deflector cannot continue to adjust the wind direction downward and can only be discharged along the direction of the air duct.

[0003] Therefore, there is an urgent need in the art for a wall-mounted air conditioner and a control method thereof to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve the above technical problems, that is, to solve the problem of limited adjustment range of the air outlet direction of the wall-mounted air conditioner.

[0005] In a first aspect, the present invention provides a wall-mounted air conditioner, which includes:

[0006] An indoor unit provided with an air outlet;

[0007] A first air guiding member rotatably arranged at the air outlet, and the first air guiding member can control the air outlet direction of the air outlet;

[0008] A second air guiding assembly provided with a grille portion, and the second air guiding assembly is movably arranged outside the indoor unit so that the grille portion can move to the air outlet;

[0009] The grille portion is provided with ventilation holes, and the grille portion can control the opening direction of the ventilation holes to control the air outlet direction of the air conditioner.

[0010] In the specific embodiment of the above wall-mounted air conditioner, the second air guiding assembly includes a main body and two rotating arms connected to both ends of the main body. The rotating arms are rotatably connected to the indoor unit, and the grille portion is arranged on the main body.

[0011] In the specific embodiment of the above wall-mounted air conditioner, the rotating arm is drivingly connected to a first driving member, and the first driving member can drive the rotating arm to rotate to control the position of the grille portion.

[0012] In the specific implementation manner of the above wall-mounted air conditioner, the opening directions of all the ventilation holes are set to face the same side, the main body is detachably connected to the two swing arms, and the main body can be connected to the swing arms in the forward direction or the reverse direction to control the orientation of the ventilation holes.

[0013] In the specific implementation manner of the above wall-mounted air conditioner, the grille part includes a plurality of louvers, and the plurality of louvers are arranged at intervals to form the ventilation holes. The louvers are rotatably connected to the main body to control the orientation of the ventilation holes.

[0014] In the specific implementation manner of the above wall-mounted air conditioner, the wall-mounted air conditioner further includes:

[0015] A second driving assembly, which is in transmission connection with the louvers and is used to drive the louvers to rotate to adjust the opening direction of the ventilation holes.

[0016] In a second aspect, the present invention provides a control method for a wall-mounted air conditioner. The wall-mounted air conditioner is the above-mentioned wall-mounted air conditioner, and the control method includes the following steps:

[0017] According to whether it is necessary to prevent the air outlet of the air conditioner from blowing directly at the human body, determine the air outlet direction of the air conditioner to avoid the air outlet of the air conditioner facing the human body.

[0018] In the specific implementation manner of the above control method, "According to whether it is necessary to prevent the air outlet of the air conditioner from blowing directly at the human body, determine the air outlet direction of the air conditioner to avoid the air outlet of the air conditioner facing the human body" includes:

[0019] When it is necessary to prevent the air outlet of the air conditioner from blowing directly at the human body, drive the grille part to move to the air outlet, and determine the orientation of the ventilation holes according to the human body position to avoid the air outlet of the air conditioner facing the human body.

[0020] In the specific implementation manner of the above control method, the step of "determine the orientation of the ventilation holes according to the human body position to avoid the air outlet of the air conditioner facing the human body" includes:

[0021] Adjust the grille part so that the ventilation holes face obliquely upward, so that the air outlet direction of the air conditioner faces obliquely upward.

[0024] In the case of adopting the above technical solution, when the grille part of the second air guiding component of the present invention rotates to the air outlet, at least part of the air blown out by the air conditioner is discharged through the ventilation holes of the grille part. By controlling the orientation of the ventilation holes, the air outlet direction of the air conditioner can be controlled. Since the second air guiding component is arranged outside the indoor unit, the adjustment range of the opening direction of the ventilation holes is larger, and the adjustment range of the air outlet direction of the air conditioner can be made larger. Moreover, by adjusting the orientation of the ventilation holes, the air outlet direction of the air conditioner can be controlled to avoid the air blowing directly at the human body.

[0025] Further, the second air guiding component includes a main body and two rotating arms connected to both ends of the main body, and the grille part is arranged on the main body.

When it is necessary for the second air guiding component to adjust the air outlet direction of the air conditioner, the first driving member can move the grille part to the air outlet of the indoor unit; when it is not necessary for the second air guiding component to adjust the air outlet direction of the air conditioner, the first driving member can move the grille part to a position where the air outlet is not blocked.

[0026] Furthermore, all the ventilation holes on the main body are arranged facing the same side, and the main body can be connected to the rotating arms in the forward direction or the reverse direction. By adjusting the connection direction between the main body and the rotating arms, the orientation of the ventilation holes can be controlled.

[0027] Furthermore, the grille part includes a plurality of louvers, and the plurality of louvers are arranged at intervals to form ventilation holes. The louvers are rotatably connected to the main body, and by adjusting the rotation angle of the louvers, the orientation of the ventilation holes can be controlled.

[0028] Further, the ventilation holes can be adjusted to face obliquely upward and can also be adjusted to face obliquely downward. This setting method can select the orientation of the ventilation holes according to the positional relationship between the human body and the air conditioner to prevent the air blown out by the air conditioner from directly blowing at the human body.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] To solve the problem that the adjustment range of the air outlet direction of the wall-mounted air conditioner is limited.

[0051] Referring to Figure 3 and Figure 4 , this embodiment discloses a wall-mounted air conditioner, which includes an indoor unit 1, a first air guide member 2 and a second air guide assembly 3.

[0052] The indoor unit 1 is provided with an air outlet 11. Specifically, the air outlet 11 is arranged on the outer wall of the indoor unit 1 and is oriented obliquely downward. The fan inside the indoor unit 1 can drive the air inside the indoor unit 1 to be discharged from the air outlet 11. The other structures of the indoor unit 1 are basically the same as those of the indoor unit 1 of the existing wall-mounted air conditioner, and the specific structures are not described herein again.

[0053] The first air guide member 2 is specifically a wind guide plate 4. The structure of the wind guide plate 4 is the same as that of the wind guide plate 4 of the existing wall-mounted air conditioner, and the specific structure is not described herein again. The first wind guide plate 4 is rotatably arranged at the air outlet 11. By adjusting the angle of the first air guide member 2, the direction of the air flow discharged from the air outlet 11 can be controlled. Specifically, the first air guide member 2 is connected to a third driving member, and the third driving member is specifically a motor. The third driving member can drive the first air guide member 2 to rotate up and down so that the direction of the air flow discharged from the air outlet 11 can be adjusted upward or downward.

[0054] Referring to Figure 5 and Figure 6, a grille part 31 is provided on the second air guide component 3, and the grille part 31 is used to adjust the air outlet direction of the air conditioner. The second air guide component 3 is rotatably provided outside the indoor unit 1. When the second air guide component 3 needs to be used, rotate the second air guide component 3 to move the grille part 31 to the air outlet 11; when the second air guide component 3 does not need to be used, rotate the second air guide component 3 to move the grille part 31 to a position where the air outlet 11 is not blocked.

[0055] The structure of the second air guide component 3 will be specifically described below through two embodiments.

[0056] Embodiment 1

[0057] Continue to refer to Figure 5 and Figure 6 , the second air guide component 3 includes a main body 32 and two rotating arms 33. The rotating arms 33 are rotatably connected to the outer wall of the indoor unit 1. The two rotating arms 33 are respectively arranged on the left and right sides of the indoor unit 1, and the axes of the two rotating arms 33 are collinearly arranged. The grille part 31 is provided on the main body 32. The main body 32 is detachably connected to the two rotating arms 33. When the main body 32 is connected to the two rotating arms 33, the main body 32 can rotate with the rotating arms 33 so that the grille part 31 can rotate to the air outlet 11 or rotate to a position where the air outlet 11 is not blocked.

[0058] A plurality of louvers 312 are arranged at intervals on the grille part 31, and ventilation holes 311 are formed between the plurality of louvers 312. The louvers 312 are all fixedly arranged to incline towards one side, so that the ventilation holes 311 are also inclined. Specifically, the opening direction of the ventilation holes 311 can be set to face obliquely upward or obliquely downward. When the grille part 31 moves to the air outlet 11, at least part of the air flow discharged from the air outlet 11 is discharged through the ventilation holes 311 of the grille part 31. Since the ventilation holes 311 are inclined, the air flow discharged from the ventilation holes 311 will incline towards the opening direction of the ventilation holes 311.

[0059] Furthermore, the main body 32 can be connected to the rotating arm 33 in the forward direction or in the reverse direction, thereby controlling the opening direction of the ventilation holes 311. Specifically, when the main body 32 is connected to the rotating arm 33 in the forward direction, the opening direction of the ventilation holes 311 faces obliquely upward; when the main body 32 is connected to the rotating arm 33 in the reverse direction, the opening direction of the ventilation holes 311 faces obliquely downward. This setting method can control the opening direction of the ventilation holes 311 through the connection method between the main body 32 and the rotating arm 33, and further control the air outlet direction of the air conditioner.

[0060] Embodiment 2

[0061] Continue to refer to Figure 5 and Figure 6, the second air guiding component 3 includes a main body 32 and two rotating arms 33. The rotating arms 33 are rotatably connected to the outer wall of the indoor unit 1. The two rotating arms 33 are respectively arranged on the left and right sides of the indoor unit 1, and the axes of the two rotating arms 33 are collinearly arranged. A grille part 31 is arranged on the main body 32. The main body 32 is detachably connected to the two rotating arms 33. When the main body 32 is connected to the two rotating arms 33, the main body 32 can rotate with the rotating arms 33, so that the grille part 31 can rotate to the air outlet 11 or rotate to a position that does not block the air outlet 11.

[0062] A plurality of louvers 312 are arranged at intervals on the grille part 31, and ventilation holes 311 are formed between the plurality of louvers 312. The louvers 312 are rotatably connected to the main body 32. By rotating the louvers 312, the opening direction of the ventilation holes 311 can be controlled. The wall-mounted air conditioner further includes a second driving component, and the second driving component is used to drive the louvers 312 to rotate to adjust the opening direction of the ventilation holes 311. In one embodiment, the specific structure of the second driving component is as follows: Refer to Figure 7 , a rotating shaft 3121 and a hinge shaft 3122 are arranged on the louver 312. A first counterbore corresponding to the rotating shaft 3121 is arranged on the main body 32, and the rotating shaft 3121 can extend into the first counterbore so that the louver 312 can rotate around the rotating shaft 3121. A slideway and a transmission part 321 are arranged on the main body 32, and the transmission part 321 can move along the slideway. A second counterbore corresponding to the hinge shaft 3122 is arranged on the transmission part 321, and the hinge shaft 3122 can extend into the second counterbore. A second driving part is further arranged on the main body 32. The second driving part is specifically a motor. The second driving part is connected to a gear 34, and the second driving part can drive the gear 34 to rotate. A rack structure 322 is arranged on the transmission part 321, and the gear 34 meshes with the rack structure 322. The second driving part drives the gear 34 to rotate, and the rotating gear 34 can drive the transmission part 321 to move along the slideway. When the transmission part 321 moves along the slideway, it can drive the louver 312 to rotate around the first rotating shaft 3121, thereby adjusting the angle of the louver 312 and the opening direction of the ventilation holes 311. This setting method can control the position of the transmission part 321 through the second driving part, and further control the angle of the louver 312 and the opening direction of the ventilation holes 311.

[0063] Thus, two specific embodiments of the second air guiding component 3 have been introduced.

[0064] Furthermore, the rotating arm 33 of the second air guiding component 3 is connected to a first driving part, and the first driving part is specifically a motor. The first driving part can drive the rotating arm 33 to rotate, thereby controlling the position of the grille part 31. In other embodiments, the rotation angle of the rotating arm 33 can also be manually controlled to control the position of the grille part 31.

[0065] Further, the main body 32 of the second air guiding assembly 3 is in a plate-like structure, and the specific shape of the main body 32 is an arc-shaped plate corresponding to the shape of the air outlet 11 of the indoor unit 1. The main body 32 is arranged at an interval from the outer wall of the indoor unit 1. In other words, a gap is formed between the main body 32 and the outer wall of the indoor unit 1. When the grille portion 31 moves to the air outlet 11, a part of the air flow discharged from the air outlet 11 is discharged through the ventilation holes 311 of the grille portion 31, and the other part is discharged through the gap between the main body 32 and the outer wall of the indoor unit 1. Specifically, a part is discharged from the upper part of the above gap, and the other part is discharged from the lower part of the above gap. For details, see Figures 8 to 10 。

[0066] When the grille portion 31 of the second air guiding assembly 3 rotates to the air outlet 11, a part is discharged through the ventilation holes 311 of the grille portion 31. By controlling the opening direction of the ventilation holes 311, the direction of the air flow discharged from the ventilation holes 311 can be controlled, thereby controlling the air outlet direction of the indoor unit 1. Since the second air guiding assembly 3 is arranged outside the indoor unit 1, the adjustment range of the opening direction of the ventilation holes 311 is larger, and the adjustment range of the air outlet direction of the indoor unit 1 can be made larger. Moreover, since the main body 32 of the second air guiding assembly 3 blocks at the air outlet 11, the air flow discharged from the air outlet 11 cannot be directly discharged. This setting method can prevent the effect of the air conditioner's air flow blowing directly on the human body.

[0067] Further, the wall-mounted air conditioner further includes a control module. Taking the second embodiment of the second air guiding assembly 3 as an example, the first driving member, the second driving member, and the third driving member are all electrically connected to the control module, and the control module is configured to execute the control method of the wall-mounted air conditioner so that the control module can control the position of the grille portion 31 and the opening direction of the ventilation holes 311 of the grille portion 31.

[0068] The control module can be only configured to execute the above control method and does not execute other operation controls of the air conditioner. Other operation controls can be equipped with other control modules; or it can be configured to execute other operation controls of the air conditioner in addition to executing this control method. That is, the control module is a comprehensive execution module, that is, it executes each program in the operation of the air conditioner system.

[0069] Referring to Figure 11 , the control method of the above wall-mounted air conditioner is introduced below. The control method includes the following steps:

[0070] According to whether it is necessary to prevent the air conditioner's air flow from blowing directly on the human body, determine the direction of the ventilation holes 311 to avoid the air conditioner's air flow facing the human body.

[0071] Specifically, when it is necessary to prevent the air outlet of the air conditioner from blowing directly at the human body, the grille part 31 is driven to move to the air outlet 11, and the angle of the first air guide member 2 and the opening direction of the ventilation holes 311 are determined according to the position of the human body, so as to avoid the air outlet of the air conditioner facing the human body. When it is not necessary to prevent the air outlet of the air conditioner from blowing directly at the human body, the grille part 31 is moved to a position where it does not block the air outlet 11, so that the air outlet 11 is exposed, and the air flow discharged from the air outlet 11 directly enters the room, improving the temperature and humidity adjustment efficiency of the air conditioner.

[0072] Taking the case where the indoor unit 1 of a wall-mounted air conditioner is installed in a bedroom as an example, the detailed steps of this control method will be described. Refer to Figure 12 , the control method specifically includes the following steps:

[0073] S101, determine whether the human head is facing the indoor unit 1. Specifically, the user can send a signal to the control module through the remote control of the air conditioner to determine whether the human head is facing the indoor unit 1; an image recognition device can also be set on the indoor unit 1 to determine whether the human head is facing the indoor unit 1. In this embodiment, the human head facing the indoor unit 1 can be understood as that the indoor unit 1 is installed on one side of the head of the bed, and when a person lies in bed, the head is located below the air outlet 11. In order to avoid the air outlet of the air conditioner from blowing directly at the head, if the head is facing the indoor unit 1, then S102 is executed; if the head is not facing the indoor unit 1, then S103 is executed.

[0074] S102, drive the grille part 31 to move to the air outlet 11, adjust the grille part 31 so that the ventilation holes 311 face obliquely upward, so that the air outlet direction of the air conditioner faces obliquely upward. Further, adjust the first air guide member 2 so that the air outlet 11 faces obliquely upward. Specifically, refer to Figure 8 , the control module controls the first driving member, and the first driving member drives the rotating arm 33 to rotate a first preset angle, so that the grille part 31 moves to the air outlet 11. The control module also controls the third driving member, and the third driving member drives the first air guide member 2 to rotate a second preset angle, so that the air outlet 11 faces obliquely upward. The control module also controls the second driving member, and the second driving member drives the louvers 312 to rotate a third preset angle, so that the ventilation holes 311 face obliquely upward. After the air flow discharged from the air outlet 11 is discharged obliquely upward and passes through the ventilation holes 311, the air flow direction deflects obliquely upward again, so that part of the air outlet of the air conditioner is discharged toward the roof direction; other parts of the air outlet are discharged through the gap between the main body 32 and the outer wall of the indoor unit 1. Specifically, the air flow discharged from the upper side of the gap faces the roof, and the air flow discharged from the lower side of the gap faces the wall. This setting method can avoid the air outlet of the air conditioner from blowing directly at the human head.

[0075] S103. Determine whether the human foot is facing the indoor unit 1. Specifically, the user can send a signal to the control module through the remote controller of the air conditioner to determine whether the human foot is facing the indoor unit 1; alternatively, an image recognition device can be provided on the indoor unit 1 to determine whether the human foot is facing the indoor unit 1. In this embodiment, the human foot facing the indoor unit 1 can be understood as that the indoor unit 1 is installed on one side of the bed foot, and when a person lies in bed, the foot is located below the air outlet 11. To avoid the air from the air conditioner blowing directly at the human body, if the foot faces the indoor unit 1, then execute S104; if the foot does not face the indoor unit 1, then execute S105.

[0076] S104. Drive the grille part 31 to move to the air outlet 11, and adjust the grille part 31 so that the ventilation holes 311 face obliquely downward, so that the air outlet direction of the air conditioner faces obliquely downward. Further, adjust the first air deflector 2 so that the air outlet 11 faces obliquely downward. Specifically, referring to Figure 9 , the control module controls the first driving member, and the first driving member drives the rotating arm 33 to rotate by a first preset angle so that the grille part 31 moves to the air outlet 11. The control module also controls the third driving member, and the third driving member drives the first air deflector 2 to rotate by a fourth preset angle so that the air outlet 11 faces obliquely downward. The control module also controls the second driving member, and the second driving member drives the louver 312 to rotate by a fifth preset angle so that the ventilation holes 311 face obliquely downward. After the air flow discharged from the air outlet 11 is discharged obliquely downward and passes through the ventilation holes 311, the air flow direction deflects obliquely downward again, so that a part of the air from the air conditioner is discharged toward the ground; the other part of the air is discharged through the gap between the main body 32 and the outer wall of the indoor unit 1. Specifically, the air flow discharged from the upper side of the gap faces the roof, and the air flow discharged from the lower side of the gap faces the wall. This setting method can avoid the air from the air conditioner blowing directly at the human body.

[0077] S105. Determine whether the left or right side of the human body is facing the indoor unit 1. Specifically, the user can send a signal to the control module through the remote controller of the air conditioner to determine whether the human foot is facing the indoor unit 1; alternatively, an image recognition device can be provided on the indoor unit 1 to determine whether the left or right side of the human body is facing the indoor unit 1. In this embodiment, the left or right side of the human body facing the indoor unit 1 can be understood as that the indoor unit 1 is installed on the left or right side of the bed body, and when a person lies in bed, the air outlet 11 faces the trunk part of the human body. To avoid the air from the air conditioner blowing directly at the human body, if the left or right side of the human body faces the indoor unit 1, then execute S106. If the left or right side of the human body does not face the indoor unit 1, then execute S107.

[0078] S106. Drive the grille part 31 to move to the air outlet 11, adjust the grille part 31 so that the ventilation holes 311 face obliquely upward or obliquely downward, so that the air outlet direction of the air conditioner faces obliquely upward or obliquely downward. Further, adjust the first air guide member 2 so that the air outlet 11 faces the direction opposite to that of the ventilation holes 311. In one embodiment, refer to Figure 10 , the control module controls the first driving member, and the first driving member drives the rotating arm 33 to rotate a first preset angle so that the grille part 31 moves to the air outlet 11. The control module also controls the third driving member, and the third driving member drives the first air guide member 2 to rotate a second preset angle so that the air outlet 11 faces obliquely upward. The control module also controls the second driving member, and the second driving member drives the louver 312 to rotate a fifth preset angle so that the ventilation holes 311 face obliquely downward. After the air flow discharged from the air outlet 11 is discharged obliquely upward, part of the air flow passes through the ventilation holes 311, causing the air flow direction to deflect obliquely downward, so that part of the air outlet of the air conditioner is discharged toward the ground direction; the other part of the air flow is discharged through the upper gap between the main body 32 and the outer wall of the indoor unit 1, that is, discharged toward the roof direction. This setting method can avoid the direct blowing of the air outlet of the air conditioner on the human body.

[0079] S107. Determine whether the grille part 31 is located at a position where the air outlet 11 is not blocked. Specifically, an infrared detector can be set on the indoor unit 1, and the infrared detector can detect the position of the grille part 31; or by recording the rotation angle of the first driving member, the position of the grille part 31 can be determined. If the grille part 31 is not located at a position where the air outlet 11 is not blocked, then execute S108.

[0080] S108. Drive the grille part 31 to move to a position where the air outlet 11 is not blocked. Specifically, refer to Figure 4 , the control module controls the first driving member, and the first driving member drives the rotating arm 33 to rotate a sixth preset angle so that the grille part 31 moves to a position where the air outlet 11 is not blocked.
